I recently bought a intake tube and an upper and lower box. I have a 2006 IS350. The intake tube does not fit onto the car and one of the pipes does not insert into the stock intake tube. I need some suggestions on what to do. I was thinking about buying an fsport intake and returning everything else. I need to pass smog soon and I have an injen which isnt CARB certified. Please let me know of any suggestions.

Also, is there a different tube for the 4-cylinder IS250 and 6-cylinder IS350? I think there is because this one doesnt fit onto my 350.

 

4 cylinder IS250? The 250 is also a V6. An intake that fits the IS350 fits an IS250.

 

What is the part # of the setup you purchased? Pictures of the pieces you received?

 

And what brand?

 

Yeah we looked up what the air cleaner hose i bought and it said it was only for the 4-cylinder IS250. So not sure.

 

Not sure the brand. Pretty sure its made by lexus and its just the stock air cleaner hose.

 

Want to take a picture so we have a better idea?

 

I've had both IS250 and IS350.. The intake is the same.

 

I think your issue is that you're missing the adapter that retrofits the stock intake tube to the aftermarket one similar to the piece all the way on the left side of the end of the tube in this picture.
